Question

The area of a circle is 49πm2. What is the diameter, in meters, of the circle?

Answer 1

Explanation:

hello :

The area is :A = πr² r : ridus the diameter is : d=2r

calculate : r 49π = πr² so : r²= 49 r=7 so : d=14 meters

Answer 2

14 meters

Explanation:

The area of a circle can be found with the formula: πr^2

We can set up an equation to find the radius, and use that to find diameter.

πr^2=49π

Divide both sides by π.

r^2=49

r=
`√(49\\)`

r=7

Radius is half of diameter, which means 2r=d

d=2(7)

d=14
